>>40555108 (OP)Physical fitness is tied to the alchemical iron, Aries, Mars, and the fourth hermetic rationality of Continence which dispels desire (lust) and being incontinent (lacking self control). Now this is what happens when physical fitness is a part of spiritual practice, this is obviously not what happens when physical fitness is ill dignified (im lifting to get pussy, to beat people up, because im addicted to it).
Ill also add that calisthenics is the western man's version of hatha yoga as it cultivates classical virtue and fine tunes self control.
Lots of spiritual implications for it, bonus points if you can do it as a devotional act and even more points if you combine it with pranayama/breathwork.
